Biography
Professor in the Department of Convergence Energy Engineering and the KU-KIST Graduate School of Converging Science and Technology at Korea University, South Korea. He received his M.S. in Mechanical Engineering and his Ph.D. in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology (MIT) in 2007 and 2012, respectively, and subsequently conducted postdoctoral research at MIT (2012–2013) and served as a postdoctoral researcher at Northwestern University (2014). He was previously an Associate Professor in the School of Energy and Chemical Engineering at Ulsan National Institute of Science and Technology (UNIST), South Korea, before joining Korea University. His research focuses on the applications of low-dimensional/heterodimensional nanostructured materials (graphene, transition metal dichalcogenides, nanowires, etc.) in high-performance energy harvesting (solar cells, water splitting, electro/photocatalysis) and emerging semiconductor technologies (nanoelectronics, nanophotonics, neuromorphic computing, sensors). Representative graphene-related achievements include a series of papers in Nano Letters (2010, 2012, on doped graphene electrodes for organic solar cells and graphene transparent conductive electrodes), a Nano Letters (2014) paper on record-efficiency flexible graphene-electrode organic photovoltaics, and a Joule (2020) paper on polyimide-integrated graphene-electrode flexible organic solar cells achieving efficiencies exceeding 15%. Related papers on graphene transparent electrodes and hybrid solar cells have been published in journals such as Nature Nanotechnology, ACS Nano, and Advanced Energy Materials, with more than 100 papers published in total and over 5,000 citations. He is scheduled to share insights at this conference on graphene-based transparent conductive electrodes and their applications in high-efficiency flexible photovoltaics/energy devices.
